For the original definition of the genus, see Note on Milne-Edwards, 1830 (p. 143). 

 For the definition of Hieraeonyx, see Note on Guerin, 1836 (p. 164). For the account 

 of CJieiropristis, see Note on de Natale, 1850 (pp. 236-239). At page 239 I have 

 accepted Spence Bate's suggestion that de Natale's " Cheiropristis Messanensis" belongs 

 to the genus Anchylomera, but it should be noticed that the figure given in the Brit. 

 Mus. Catal. Amph. Crust., pi. Iii. fig. 4, with the name Anchylomera sedentaria, and a 

 reference to " Phronima sedentaria, Costa, Pochi Crust, del Messina," has nothing to do 

 with Cheiropristis messanensis; it is in fact a reproduction of the "Phronima Coccoi" 

 figured in de Natale's Lettera 1 al Sig. Achille Costa, Su pochi Crostacei del porto di 

 Messina, and represents a true Phronima of the male sex. 



To the definition of the family Bovallius in 1887 adds only a few words for the 

 definition of the genus, as follows : — 



"The first two pairs of pereiopoda \_First and Second Gnathopods~\ simple, the third, 

 fourth, and fifth pairs [First, Second, and Third Perieopods~\ subcheliform. The uropoda 

 are rounded behind." 



To these characters it may be added that the female is distinguished from the male
